In February of this year, the world lost Leonard Nimoy, one of film and television's most prolific space explorers and everyone's favorite half-Vulcan, Mr. Spock.

While it's still difficult to cope with the loss of such a great man, Star Trek fans can take some solace knowing that his co-stars are keeping his memory alive even after he's gone.

Earlier this month William Shatner, the Captain Kirk to Nimoy's Spock, posted the following photo on Twitter asking his followers to take a selfie holding up the Vulcan "live long and prosper" salute, without much explanation.

In 2010 Supernatural's Mischa Collins started GISHWHES (Greatest International Scavenger Hunt the World Has Ever Seen) a worldwide scavenger hunt which has people compete in a week-long scavenger hunt of tasks, ranging from difficult to nearly impossible. GISHWHES aims to remind us that even the most ludicrous and seemingly unattainable things are within our reach if we get creative and work together.

Since GISHWHES' inception, numerous stars like Shatner have gotten involved and proved that the world is a much smaller and friendlier place than previously thought. As a lifelong lover of arts, science, and humanities, I think that Leonard Nimoy would appreciate that sentiment.
